1.	`DeltaH_(comb)^(@)` of carbon is `-x kJ mol^(-1)`. The standard formation of enthalpy of `CO_(2)(g)` will beA. `-xKJmol^(-1)`B. `+xKJmol^(-1)`C. `-x//3KJmol^(-1)`D. Data is insufficient to predict it
Answer» Correct Answer - B `C(s) + O_(2) (g) rarr CO_(2)(g)` `Delta H_("comb")^(@) = -x kJ//mol` `-x = DeltaH^(@) (O_(2)) - (0 + 0)` `DeltaH^(@) (O_(2)) = -x kJ//mol`
